This invention relates to a gate construction and more particularly to a construction wherein the principal object is to provide a gate having intermediate cross members which are of flexible material, so that the entire gate can be pulled back towards one side.

A further object is to provide a gate construction which will return to normal closed position upon being released by the operator.

With the foregoing and other objects in View, as will appear as the description proceeds, the invention consists -of the novel construction, combination and arrangement of co-operating elements as hereinafter more specifically set forth, claimed and shown in the accompanying drawings forming a part of the present application, in which:

Fig. 1 is a side plan View of the preferred embodiment of my invention.

Fig. 2 is a top plan view of 'the operating means used in the preferred embodiment of my invention.

Fig.l 3 is a plan view of one of tlie'hangers.

Like numerals of reference designate corresponding parts throughout the different views.v y

At opposite sides of' the gate, I provide uprights 4 and 5, having their lower ends imbedded along the side of the road bed.

The upright 4 is slightly higher than the upright 5 and extending from the top of the upright 4 to the top of theV upright 5, I provide a cover member C. This cover mem 'her C acts as a cover over the working parts,

' and overthe track, as well as bracing the upper ends of the uprights 4 and 5 in their proper relationship to each other. On either sides of the upright 4` ,l provide uprights 6 and 7 having outwardly extending brackets 8 and`9 respectivelv. The lower ends of these uprights 6 and 7 are imbedded along the side of the road bed.

10 is an inclined track extending in parallel relationship to the cover C and having its opposite ends securely engaged, one near the upper end of the upright 4 and the other near the upper end of the upright 5. 11` 12 and 14 are hangers of U-shaped formation. 15 is a wheel mounted between the upper ends of the U-shaped member 12 and adapted to roll on the track 10. 16 indicates smaller rollers rotatably mounted intermediate the wheel 15 and the lower end of the U-shaped portion of the hanger 12. The purpose of these rollers will be hereinafter mentioned.

tion. y

ner face of the upright 4 andto whichthe' 17 is an eyeebolt supported from the lower portion of the U-shaped hanger 12. 18, 19 and 20 are supporting cables having their upper ends attached to the eye-bolt 17 and the hangers 11, 12 and 14 respectively. The

lower end of these supporting cables are attached to a suitable eye-bolt engaged in the ends of the suspended uprights 21, 22 and 23, which uprights are provided with intermediate llexible connections 24, 25 and 2 6.

vThe upright 5 is provided, on its inner face, with guide lingers y27 into -which the upright 23 normally positions itself when the gate is closed and if desired a pin 28 may be transversely inserted through oppositely registering openings in the lingers 27 so as to retain the gate in closed posiy 29 is an upright secured to the ininner ends of the flexible connections 24 are attached.V

30 and 31 indicate flexible cables, each having one en d secured around one of the smaller rollers 16 in the hanger 14.` These cables 30 and 31 extend upwardly over their respective smaller rollers 16 in the hangers '12 .and 11. They then extend through their respective pulleys 32 and 33,' extending outwardly then in approximately opposite directions towards the bracketsS and 9. Each bracket is provided with a pulley 34 through which the cable will extend and hang downwardly therefrom. Each cable is provided with a suitable weight 35 near its free end.

36 is a. buffer suitably supported inwardly from the upright 4 and provided with a spring 371 so that if the hangers 11, 12 and 14 are'pulled up quickly, they will strike against this buffer 36 and when either Vof the cables 30 or 31 are released this spring 37, havin-g been tensioned, will repel the hangers outwardly on the inclinedtrack 10 so as to quickly return them to their normal position. thus closing the gate quickly.

The foregoing specification and loo annexed drawings disclose the preferred embodiment of my invention, but it isvtov be understood that minor changes may be resorted tg in the commercial adaptation of my invention withoutV departingv from the scope 'of the invention as hereinafter claimed.

What I claim as new is:

A gate comprising uprights suitablvk braced at their upper ends; an inclined track supported between the upp'er ends of said uprights; hangers reciprocally mounted on said track; cables extending through said hangers and one end secured to the outer one of said hangers; the said cables extending v'through ulleys supported on one of said u 5 rights a jacent the upper end of said tradi); brackets lsupported lon uprights spaced e uidistant from saidv last mentioned uprig t; pulleys supported from each of said brackets; the ends of said respective cables extending uprights supported fromrthe lower end of said suspension members and flexible conneetion means between said gate uprights.)

In testimony whereof, I aix my signature.

CARL ARVID CARLSON.
